The worthlessness of Vitamin D is mildly exaggerated

Re: The worthlessness of Vitamin D is mildly exaggerated
#52This is a refreshingly balanced and honest analysis of Vitamin D studies. The strongest evidence for Vitamin D is in people who are severely deficient. Bumping up to a normal range can provide some improvements. The health influencers started noticing that the Vitamin D studies coming out weren't matching their original hype for Vitamin D, so many pivoted to trying to make claims that most people are severely deficie…
On a slight tangent, if people are unaware, you can pay for and get just about any lab test without a prescription in the United States.
You can get most tests (although often not genetic) in many countries, with Canada being an outlier in forcing you to get a doctor’s note for just about everything.

#53Your body needs vitamins in order to form complex aminos to operate. But your body only needs to make so many of them - especially if you are an adult, not pregnant, or not suffering from a disease of some sort. The very premise that loading up your body with "excess" vitamins beyond what you need is already pretty fraught. Building a house without enough lumber can lead to long term deficiency - but loading up a con…
> loading up a construction site with more materials than are needed shouldn't automatically be assumed to be good
It is almost universally recognized as good to do exactly that. It's better to have one planned extra trip to return excess materials (if they can't be used on the next job) than to have multiple unplanned trips when you unexpectedly run out of this or that.

Re: The worthlessness of Vitamin D is mildly exaggerated
#55I suspect that blood vitamin D is mainly a marker for how much outdoor exercise people are getting, and that it is the exercise rather than the D which is causal.
Maybe this is true if you’re only considering white people. Brown people can spend a lot of time outdoors and still be deficient, especially if their ancestry is from much a much sunnier region or lifestyle than the one they’re currently living in.
Indeed: “Vitamin D deficiency in western dwelling South Asian populations: an unrecognised epidemic” … “27–60% of individuals, depending on season”

Re: The worthlessness of Vitamin D is mildly exaggerated
#56It's arguable whether Vitamin D is really a vitamin or a hormone, see https://pubmed.ncbi.nlm.nih.gov/33549285/ Look at the molecular structure https://en.wikipedia.org/wiki/Vitamin_D that's a freakin' steroid with one of the bonds in the rings deleted https://en.wikipedia.org/wiki/Secosteroid
It's pretty well-established science now that vitamin D is a hormone, not a true vitamin. Vitamin D binds a nuclear receptor that regulates roughly 1,000 to 2,000 genes (5-10% of the human genome). The "Vitamin D" moniker has just stuck around since it was named in 1922.
Yeah, it's just a holdover, the term "vitamin" originated from "vital amine", and vitamin D doesn't even have an amine group

Depends on which vitamin as well. Some like vitamin B and C aren't retained, so excess is shed quickly.

Probably due to road conditions during the winter season. Imagine asking someone who isn't used to driving on icy roads to drive a large van full of equipment up through the Rockies
Re: The worthlessness of Vitamin D is mildly exaggerated
#59Just mildy exaggerated? Is this a joke article? If you don't achieve a suitable level, health will suffer immensely, even permanently. There are no ifs and buts. People who say otherwise work for the medical industrial complex and will get you killed. Note that adequate magnesium is critical for proper vitamin D function, but the article doesn't document it.
Same for breathing oxygen, if you don't get it you'll die, but for most people oxygen supplementation would not be worth even knowing about.

#60I like this author but this post was only weakly intriguing. More importantly, I'd like to know how long it takes to write a post like this. Everything I write, I try to research and publish in under 2 weeks. This post looks like it grew over time. I like that quality very much.

In this case, about three weeks.
